Not tested yet, but thanks. The old version worked well in Windows and Linux, so I assume this contains improvements?

Sorry the improvements are not the main part of this release i changed the thread modell of the lib and use more CPU instuctions so i need feedback from diffrent OS's (98se,Me,XP,2000/NT,Linux) and diffrent CPU's 486-XXX with diffrent clock rates.
If your tests works all right i will not change the plugout interface and put the missing DSP and networkstreaming in the lib.
You know

Everything seems to work except for Test3 which crashes when it exits:
| Quote: |
debug: fbs:exit
debug: mm2:stop
debug: mm2:exit
debug: fbs:~
debug: cpu:~ <- crashes here.

Win2k Pro, AMD 1.1 ghz, 256 mg.
I tried looking at it in Insight, and I get a heap error:
All the other test worked fine. That fractal program is very hypnotic. Nice job on this. |

rdc please try this i added fbs_destroy_wave on then end.
Thanx Joshy

I believe that XP uses a method called thunking for it's sound timing accuracy, and 2000 uses pure 32 but timing. not sure if it's relevant but it's sound related, so maybe. :-) |

MystikShadows thanx for your info but the playback/latency seams to be ok.
after mm2:stop ' all sounds are off and all threads are exit
after mm2:exit ' the device are closed
after mm2:exit ' all memory are free
and fbs:~ is the libfbsound.a destructor
and cpu:~ is the libmmncpu.a destructor <- crashes here.
sub mmncpu_exit() destructor
dprint("cpu:~")
end sub
prints only a debug message on stderr
I have no 2000 and can't debug it :-( |

This is what I get:
| Quote: |
(gdb) r
Starting program: C:\Languages\FreeBASIC\examples\fbsound\test3.exe
warning: HEAP[test3.exe]:

It is the same error I get in Insight. Here is a pic of the registers at the crash. Not sure if it tells you anything.
It seems to me there may be a Null pointer being referenced somewhere. Of course if nobody else is getting this error, then it may be with my machine. As I said, all the other examples are working. I am not sure that anyone would ever try and load 100 sounds at the same time, so I am not sure this is all that critical. |

It appears the problem is in the test program, not the lib calls. I did a simple for-next calling FBS_Play_Wave and FBS_Get_PlayingSounds() and it worked perfectly. As soon as I put it in the Do-Loop, it crashes. Could there be some asm conflicts with a Do-Loop? The for-next worked just fine.
Edit: The problem seems to be with FBS_Get_PlayingSounds() being called in a loop. I replaced the Do-Loop with a goto and it still crashed. If I don't call the function I don't get a crash. |
